Zaken is the epic boss of Devil's Isle. He lives in his pirate castle on the island, and when he appears he fills its 15 rooms with 220 minions. He first appears in Chronicle 10 (Hero's Arsenal). Before that, the castle is closed.
After a kill, Zaken comes back about 48 to 72 hours later, always between 21:30 and 22:30 (server time), at a random minute. He stays until someone kills him. The raid boss list in the Community Board shows the earliest time he can appear.
The castle
The castle has 15 rooms on 3 floors, 5 rooms per floor. When Zaken appears, he fills every room with minions. A minion that dies comes back next to Zaken 30 to 90 seconds later, as long as he lives.
Day and night
Zaken follows the in-game clock. Night lasts the first 50 minutes of every 4 hours: 00:00-00:50, 04:00-04:50, 08:00-08:50, 12:00-12:50, 16:00-16:50 and 20:00-20:50 (server time). The rest of the time is day.
| Time | What Zaken does |
|---|---|
| Day | When his HP drops below 75%, 50% and 25%, he jumps to a random room of the castle and forgets everyone who attacked him. Find him and continue. |
| Night | He casts Zaken Regeneration: 20 times his normal HP regeneration, 50% more P. Def. and M. Def., and he heals 25% of the damage he deals. He also moves between rooms on his own. |
Zaken's weaknesses
| Weak to | Effect |
|---|---|
| Daggers and bows | Zaken takes 25% more damage from dagger and bow attacks. |
| Magic | His physical defence is almost three times his magic defence, so magic gets through more easily. |
Zaken has no element. No attribute does more or less damage to him. He is Undead, so undead-only skills such as Disrupt Undead can target him, but no skill gives bonus damage against the Undead.
What Zaken resists
Zaken has 90% resistance to stun, sleep, root, paralysis and fear. These almost never land, so do not waste them. All his minions have the same resistance.
How Zaken fights
Zaken is aggressive: he attacks anyone on his floor who comes close.
| Skill | What it does |
|---|---|
| Deadly Dual-Sword Weapon | A very heavy hit on the player he is fighting. |
| Deadly Dual-Sword Weapon: Range Attack | Hits everyone standing right around him. |
| Absorb HP MP | Drains HP from the target and the players right next to it, and burns their MP over time. |
| Hold | Roots the target for 30 seconds. |
| Scatter Enemy | Teleports the target, and sometimes other players on the same floor, into random rooms of the castle. |
The minions
Zaken's 220 minions are all level 80 and aggressive: they attack anyone on their floor who comes close. They are weak one by one, but there are many and they come back fast. Their hits deal Dark damage.
| Minion | Count | Race | Weak to / resists |
|---|---|---|---|
| Pirate Zombie | 103 | Undead | Weak to Holy attacks |
| Vale Master | 47 | Demon | Resists bows (half damage) and Dark attacks |
| Pirate Zombie Captain | 36 | Undead | Weak to Holy attacks |
| Doll Blader | 34 | Demon | Resists bows (half damage) and Dark attacks |
